SPECIFICATION forming part of Letters `Patent No. 399,652, dated March 19, 1889. Application filed October 15, 1887. Serial No. 252,452. (No model.)

To @ZZ whom t may concern.-

Be it known that I, ALVIN O. OARMAN, of Potterville, in the county of Eaton and State of Michigan, have invented certain new and useful Improvements in Harvester-Reels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it app ertains to make and use the same.

My invention relates to an improvement in harvester-reels.

The object of my present invention is to provide simple and efiicient means for inclining the blades of the reel, so as to straighten up inclining grain.

A further object is to produce mechanism by which the blades of the reel may be inclined in either direction and at any inclination desired.

lVith these ends in view my invention consists in the novel construction and peculiar combination and arrangement of parts, as will be hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is an end elevation. Fig. 2 is a sectional view. Fig. 3 is a view on line .fr r of Fig. 2.

A indicates a reel-shaft, provided at its free end with a rigidly-secured plate, B, having two annular flanges, C C', made integral therewith and projecting' forwardly therefrom, this plate B and the flanges C C forming a head, as shown. The flange C is preferably located within and concentric with the iiange C and removed a suitable distance from the latter to produce a space or chamber, D, between the two flanges, as shown in Fig. l.. A hollow hub, E, is preferably formed at the center of the plate B, concentric with the flanges C C', and within this hub the shaft A extends.

The outer flange, C, of the plate B is provided throughout its circumference with a series of perforations, b,for the reception of one end of the reel-arms F. The inner extremities of these arms, also passing through perforations b of the flange C', are thus journaled in both flanges, C C. Aserics of bevel# pinions, c, are fixed to the arms F between the flanges C C', and by being thus secured to said arms the latter are prevented from becoming displaced. The plate B is further provided with a series of preferably elongated slots, d, through which the pinions c are adapted to project slightly, for a purpose to be described. l

The outer ends of the arms F are split for the reception of the reel-blades G, which are secured to these arms and project. at right angles thereto an equal distance on each side. By thus securing the blades to the arms of the reel the use of brace rods and stays is obviated, as such rods produce a hinderance to the proper operation of the machine, and are more or less clumsy or weighty.

Iioosely mounted upon the shaft A, in rear of the plate B, is a sleeve7 II, havinga means for connecting' an operating-lever at its rear end. This sleeve or collar is provided at a point between its ends with an elongated slot, c, a pin, e', being secured to the shaft A and adapted to work in the slot e, to prevent the sleeve from rotating independently of the shaft or sliding too far.

The forward end of the sleeve II is provided with a series of inclined fingers, H", having slots I-I2 between them for the reception of a series 0f interlocking lingers, I, formed on a hub, J, of a loosely-mounted toothed wheel or disk, K.

The wheel or disk K is provided on its forward face near its periphery with a series of bevel-teeth, f, which mesh with the bevel-pinions c, and turn the latter when the wheel K is actuated.

It will be seen that when the sleeve H is slid backward or forward upon the shaft A the ngers H I will engage each other, and by their reversely-inclined positions and the sleeve II being prevented from rotating independentlyv of the shaft the wheel or disk K will be turned, and consequently the pinions c. This operation will cause the arms F to turn with the pinions c, and the blades will be deflected from a plane parallel with the finger-bar and may be held at any angle desired.

Vhen the grain stands in an upright position, the blades l. need not be inclined, as there is no necessity therefor, but when the grain has been blown over by the wind and inclines toward either side of the machine it IOO is essential that the same should be straightened. If the grain should incline toward the grain-wheel, the blades are inclined, so that the ends of the blades nearer the grain-wheel will approach the cutters first and thereby gradually force the grain against the cutters. The blades should be so inclined that the stubbleward end of one blade is practically on a line with the grainward end of the next, so that when one blade leaves the grain the next blade will take it up in the same manner as the first blade. If the grain should ineline in the opposite direction, the blade should be inclined in the opposite direction from that above described, so as to cause the ends of the blades near the ground-wheel to approach the cutters. By these means I am enabled to lay the grain perfectly straight on the table,which is very important where binding mechanism is attached to the harvester.

It is evident that slight changes might be made in the constructive details of my invention Without departing from the spirit thereof or limiting its scope; hence I do not wish to limit myself to the precise details of construction herein set forth; but,

Having fully described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. In a harvester -reel, the combination, with a shaft, of a flanged plate secured to the end of the latter, reel-arms journaled in the flanges, pinions fixed on the arms, and means for actu ating said pinions, substantially as set forth.`

2. In a harvester-reel, the combination, with a shaft and a flanged plate secured to the end thereof, of a series of reel-arms journaled in the anges of the plate, pinions fixed on said arms, a toothed wheel or disk loosely mounted on the shaft to engage said pinions, and means for actuating said Wheel, substantially as set forth.

3. In a harvesterreel, the combination, with a shaft and a plate secured to one end thereof and provided with two annular flanges, one Within the other, of a series of arms journaled in said flanges, these arms having blades thereon, pinions on the arms between the flanges, and means, substantially such as de-` scribed, for actuating said pinions to incline the blades, substantially as set forth.

4. In a harvester reel, the combination, with a shaft having a head secured thereon, and arms journalcd in the head and provided with pinions, of a gear-wheel loosely mounted on the shaft with its teeth meshed with the teeth of the pinions, and a sliding sleeve mounted on the shaft and interlocked with the gearwheel, and adapted by its sliding movement to turn the gear-wheel, substantially as set forth.

5. In a harvesterreel, the combination, with a shaft and a flanged plate secured at one end thereof, of a series of arms journaled in the flanges of the plate, pinions on these arms, a gear-wheel loosely mounted on the shaft adapted to mesh with said pinions, said toothed wheel having inclining fingers thereon, and a sleeve adapted to slide on the shaft, said sliding sleeve also having inclining fingers adapted to interlock with the fingers on the toothed wheel, and mechanism for sliding the sleeve, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
